Have you flushed your line with saline? I have had blood in my line many times. Usually it happens when I do alot with my arm. I just flush it and it goes away...
This works even if the blood has been in the line for a long time...did you forget to flush? When I first started doing my IV I would forget to flush first and the IV wouldn't work. I hope this helps!

The line would clear right away, but within an hour it would fill back up. They couldn't explain why that was happening, but as long as I could flush and infuse without difficulty, they were not worried about it.

I was flushing up to 8-10 times a day, but I made it to the end of 56 days. I had the line pulled last week and it looked fine when it came out! Who knows?

Good luck and I hope the problem straightens out for you.

We then tried flushing it with heparin. That worked.

Houston we have contact! The mission was accomplished. I now have my daily dose of rocephin.
